Mediators of a Mindfulness-Based Intervention for Younger Breast Cancer Survivors: Effects on Depressive Symptoms

Depression is associated with poor outcomes in breast cancer patients, with higher prevalence among younger women. While mindfulness-based interventions (MBIs) have demonstrated therapeutic effects, the mechanisms of intervention effects are poorly understood. We investigated whether rumination, self-kindness, intrusive thoughts about cancer, cancer-related worry, or meaning and peace mediated intervention effects of a MBI, Mindful Awareness Practices (MAPs), on depressive symptoms. Additionally, we explored the same variables as mediators of a psychoeducation program, Survivorship Education (SE).
